"In all situations, disinfection performance really should not be compromised in attempting to fulfill suggestions for disinfection by-solutions, or in trying to cut back concentrations of such substances."

If ammonium is current inside the water at enough time of chlorine addition breakpoint chlorination will never take place right until all the ammonium has reacted Along with the chlorine.
